How to Repair or Unlock ATMEGA64 on Xprog M

Here’s the customer solution to help users solve the problem xprog atmega64 locked and can not read or program chip issue.
This is done off board with qfp64 breakout board should be able to  program onboard xprog also though.

Disclaimer:  Many thanks dil6222 from cartechnology.co.uk forum. You are at your risk.

Easy fix all you need is:

1. UPA USB PROGRAMMER

2. USBASP WITH SLOW CLOCK JUMPER ON
EXTREME BURNER SOFTWARE AND 10 TO 6PIN ADAPTER

3. JUMPER WIRES FEMALE AND MALE

4.QFP64 BREAKOUT BOARD

let’s get started 

1.     First of all connect jumper wires between atmega and usbasp
you will need to split vcc + into 3 wires and gnd – into 3 wires

Connect vcc+ to pin 21,52 and (64 i believe optional as for avcc i test later)

Connect gnd- to pin 22,53 and 63

Connect SCK to SCK

Connect RESET to RESET

MOSI to PE0    (common problem is people using PB2 and PB3 as there listed as mosi and MISO but they are not )

MISO to PE1

You should end up with something like this .  you can see I’ve split the and vcc

2.   Next connect PIN2  from UPA DB9 SOCKET to XTAL 1.

Now connect everything else usbasp and upa to usb etc

Now comes the fun bit

3.   Open upa software go on tools then pulse generator and you will see this:

Change frequency to 1000khz and click start and leave it running.

4. Open extreme burner avr and go to fuse settings tab and click on read
atmega should connect as normal

5. Go on each set of fuses low, high, extended lock go on bit details and click load default value for each set
Then tick all the write boxs and click write.   or you can manually enter the following
(  Low E1,  HIGH 99, EXTENDED FD, LOCK FF then click write these are factory lockbits. see photo

6. Go on low fuses and check the following clksel settings are  there

Cksel0   (1)
Cksel1   (0)
Cksel2   (0)
Cksel3   (0)

Now erase chip and then disconnect upa

That’s it all done it should be able to program/ read as normal without upa sending signal to xtal1 on mega.

Hope this helps many users to unlock Xprog atmega 64.

Mercedes W203 4J74Y ECU Pinouts to Xprog UPA

This is pinout of EZS 203 545 01 08, using ECU programmers Xprog or UPA USB programmer.
Mercedes W203 mask 4j74y



I usually use rosfar pinouts transfer pindata to Xprog. UPA read only first mcu..for second need security bites

4J74Y W203



W203 1J35D R270 BDM programmer



W203 1J35D (xJ74Y)



EIS W203 1J35D pinout Xprog-M



Yes, you can have luck to read w204 eis with Xprog and erase the flash. But many talk about their failure with W203 mask 4j74y and Xprog, coz there are many versions of Xprog box programmer clone – quality differs and depends. Have a HQ clone then go for 4j74y. therwise, you would have reading error and hear beep beep.

So, Xprog is not so good with HC908. Some never got Xprog to work with HC908 in circuit. They tried and had no success to read this mask at with XPROG, usually they went with R270 programmer to read it finally – R270 without a problem (I think the new R290 or R280 should have no issues also. And R290 is better for future use.)



In sum, for 4J74Y W203, the best is ETL/R270 progrmmer, then Xprog m.

How to Renew Volvo XC90 ECM by Xprog or UPA

Question before entering:
I have a 2003 XC90 ECM that I need to clone or renew a used unit.

I have xprog, upa, and galletto

Very new to this, only used galletto so far

Can someone instruct me?



Solution:
Read eeprom from the original and write to the donor. or exchange eeprom.
if it does not have to be eeprom 5p08 or 95160.
Try to find marked as 5p08 to identify the immo eeprom which is to be read.



xprog and upa usb programmer great read eeprom 5p08 . solder eeprom

Try look under ST chip, the last one … it read and write just fine!



Result:
Quick update. Read the original ECM eeprom, loaded on to donor eeprom with UPA USB programmer.
Soldered eeprom to donor ECM. Vehicle started.

Note: If have ECM software faults.
Had to do ECM reload with Volvo VIDA software.
Car is running great now!

Hope it helps!
